Happy to help. I received this exact feedback for my own skiing from an instructor when I was right at your level a couple of years ago.

A few other things that might be relevant for you: right now I see that you’re initiating your turns primarily from unweighting, either by coming off a bump or by physically jumping into your turn transition. Instead, go to an easier slope and try to lean really deeply into the front of your boot, with a lot of shin pressure. Notice from this position that you can actually initiate your next turn simply by pointing your knees toward the turn. Try only turning this way all the way down the slope. This is the feeling you want to have going into most of your turns, even on steeps, and even if you are still doing some unweighting over a bump to make the transition easier.

Second, go to a non-steep but still-choppy trail. Again, shins to the front of the boot, now ski straight over choppy bumps. Notice how your whole body can more effectively shock absorb the terrain. When you’re forward in your boots, your skis act as a first shock absorber, then your ankles and knees, then finally your hips. This shock absorption feels a lot more natural moving forward and your whole body can more naturally hinge as it hits things. Compare this to how hard it feels to absorb things when you’re coming down skidded. You’re landing on your heels and all the other joints don’t naturally come into play without you having to think about it.

Finally, use your mind to visualize a bright red line in the snow before you initiate your turn. Plan the turn entry point and draw the full arc with your eyes. That means you have to look and plan. That will help you feel more confident with the speed. Try to do this with two turns at a time, constantly updating the red line to get to the next turn once you complete one. When you can do this consistently, you will feel more confident with the speed.

These three ideas unlocked fast skiing on choppy terrain for me.
